To all whom it may concern:

Bait known thzifil, LANSllblG@NDERJJONK, a citizen of the Units-1i States, residing at New-York, in the county of New York, State of New York, lmvo invented ooi-toin now and useful linprm'omcnts infivorsoalmi 11g Sowing- Machines, of which the following iSuL (icsci'iption, rolorenco being llfMl to the accompanying (ll-owing; and to the letters owl figures of reference marked thereon.

- My invention relatcs to on improvement in sewing machines, and ospecialllyto thoso I of the zigzag, oycrsean'iing; or button liolc type, and the object is to provide a machine ol' the type rciorrol'to, which in 11y no odopt-- cclto Ina-ho a chain stitch.

In other words, my improve-moot enables the machines to accomplish doublo tho moonlit of work possible in o oinglc medic machine. in button hole [machines when used with a, oing'lo lOOpOI, it has tho o-zlvantogo of l11(}1'8ling the size of the purl cast on tlio under side of the material 01 the i'oosolii that two noodlo 'tlncmls will ho tie-ll up with a. single looper thread which Will noportionotoly incroaso sizo of the purl from that of a single need c ticd-up with tho loopci throoil.

Referring to Fig. 1*,Athe frame lfgooseneck 2,1'ncedle lever 3, needle, -har'gate or frame 4, needle bar 5 needle cam'fifand gears 8 and 9 are all of therusual' construction ofthe well knownUnion Silecial overseaming machine.

As shown in this Fig. 1, and in Figs. 3, 4, and

5, the needles 1 1, 11, are arranged one back of the other and in the direction of the feed, but a single looper 16, and that traveling in the direction of the feed, and cooperating to take a loop of needle thread from both needles, is used. As the looper runs in the di- ,l'BCtlOl'l of the feed it is desirable that it should have a movement in unison with the zigzag movements of the needles, in other Words, that it should have a needle following movement, and this is imparted as follows: 1 A represents a pltman having at its forward end a ball joint connection with the needle bar gate, or frame 4, and at its opposite, end

, having a similar connectionwith the upper I slot connection (shown in Figs. 7 and 8) with the upper end of the lever (J. The link 17 is divided, the two ends embracing between them the slotted head 18 on the upper end of said lever C, and through the divided ends 19 of the link 17, and the slot 20 passes a screw bolt 21, having a thumb nut22, on the end bearing against a washer 23, and. by this ad-;

j ustmeut the amountof throwof the lever (I is adjusted, this lever U being pivoted at c to the frame vof the machine. This is a convenient arrangement but not absolutely necessary.

To the lower end of the lever C is attached by a ball. andstud connection a head 24, having a socket into whlch is screwed a. short rod 25, having at its oppqsite end a ball 26, which fits Within the end- 0f a block 27, secured to the end of-the lotperlshaf t I, having sliding and rocl-zing hearings in thelugs 28. As the needle bar gate or frame 4 is us cillatod the shaft P throu lithe connections above described, will here 'iprocated, andas the shaft P is oscillated, as hercinafterdescribed, such movement will be allowcd'thc block 27 turning around, the ball 26. This arrangement marked 25,26, and-27 is similar to and may be exactly the same as the arrangmncnt shown in patent granted 1t. Stoekor, May 12, 1897, #583,391 To the forward end of this sliding, and rockingshaft l is fixed a, looper supporting frame 0 shown in detail in. two different positions in Figs 9 and 10. This f ramc O has a sleeve portion 2%) rigidly fixed upon the end of the shaft P.

,or lug 30 extending-downwardly from From the theneedles Wi I threads. ;The looper supporting frame 0 haiv an opening 35, through it, arranged at an int This looper support or frame '0 has an a irln iv e sleeve 29' and secured upon its'lower end is a. stud having a ball head 31, over whichfits oneend of a two part link or bar D, and at its opposite end this link or bar D is clamped over a ball sleeve 32 on the stud H, which stud H is secured in thearm 33 of the caq'nk J which is'fixcd onthe forward end ofthe main driving shaft K. The looper 16 is stipported in a socket 34 in the frame 0, ind from the construction just described it be seen that as the driving shaft K rotaics,

the-bar D oscillates, and impartsan osoil lating motion through the arm '30, and'frame O to the shaft P, thus givin theforwar'd and backward movements totlie looper, and! at the same time the shaft Pwill reciprocato'in the direction of its length to move the looper sidewise in unison with the lateral vibrat on of the needle. 7 a

' Instead of the pitman A, it will be unddnstood that a connection may be rovidcd iletween the pitman 6, or the oscil ating frarh'e to which it is attached and the lever B, so that the looper following movement may ble transmitted therefrom, the pitman A being omitted. i i i As a further and special improvement in machines of this character, I have provide t,

loop spreader which istsupp'ortcd by the. loopor supportingframe, but has an osc'illatory motion. on its own axis across the plane of the looper to s read the looper thread so that the needle t ireads ivill eo -air it, said s reader also being arranged to 0 ji the needle'l'oo s back on the looper so that ll not interfere withtheir own cline tothe socket 334 to receive the shank of a loop spreading device 36, this shank having seeuredat its upper end a collar, 37 which rests upon the upper portion .of the looper l supporting frame 0, said shank extending stud 41, secured in the head of the crank 42,, which crank 42 passes through and is so-x.

cured in the head 43 of the bol blilng Se-v cured therein by the screw'44, thisbeing the samcbolt H w rich supports the ball sleeve 32. .By this, connection it will be noticed its" opposite end embraces the ball 40, on the that as the (lrivinmshaft K rotates and-the I looper has an sci latiug movementwin the direction of its length impartedto it, as'well as a sidewise'movement to follow the movements of the. zigzag-needle, that the loop.

spreader, besides traveling bd ily with'the loopcr will have an oscillatory ovement in the socket or hearing on its" own MUS means names the path traversed the loeper. t cate the leeper 100p and move it to one side to form a triangle into which the needles will.

pass and to hold the needle lumps been an the loopsr until such time danger ni the needles i1 terfsring; with their nwn lee-es has passed.

ln addition to other fest-nine set forth, .l. believe 1 sun. the first to invent :2, leop spreader supported by the looper snpi iorting frame and having bodily movement with the 106ml Ia'nci having sn independent mnveinent on its .ewn axis. Two terms of loop spreader m "herein illustrated, one in 5 and the ether ,in Fig. 5, in the former the point 0? the loop merely pssses into the path of the; the angular needle thread to proper pesitien; in Fig. 5"

the paint or end of the loop spreader has a.

noteli which positivelyengeges the loeper thread and l erees'it away from the leaner n certain distance, afterwhich the inoperthrencl is left tn drswe'll the incline as the looper and spreader move "back.
